Folded bill printing method convenient for printing precision checking

The invention provides a folded bill printing method convenient for printing precision checking, comprising the following steps of: transporting paper by a winding drum, printing in a plate-making way, stamping an edge hole, pricking and pressing a tear line, and folding the bill in a collection way. Two triangular marks which are opposite to each other and separated from each other left and right are printed on the surface of each bill when the bill is printed in a plate-making way, and a peak connecting wire between the two triangular marks is just to be the tear line between the adjoining bills. When the bill is printed, the two triangular marks are printed on each bill at the same time, and the peak connecting wire between the two triangular marks is just to be the position for pricking and pressing the tear line, so that the error of the printing can be very conveniently known after the bill is folded in a collection way. The equipment can be timely and conveniently adjusted, so that the work efficiency can be improved, and the quantity of waste product can be reduced.
